I have contemplated applying that principle, so as to distinguish it from other inventions.4

My inventionrelates to apparatus used in the manufacture of gas, and particularly to producers for manufacturing semi-watergas. y

The object of the invention is to increase ,l the economy of production of suoli semiwater-gas, and particularly with reference` to the continued production of a uniform quality of such gas.

The said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawing` and they following description set forth in detail certain means for carrying out my invention, the disclosed,

v.to

means, however, constituting but one of varieA ous mechanical forms in which the principle of the invention may be applied.

In said annexed drawings :'-Figure l represents diagrammatically an apparatus elnbodying my invention, Fig. 2 is a detail of a modification, and Fig. 3 is a diagrammatic illustration of a modified 'form of my invention. Y

The apparatus illustrated in the drawing, and to which m invention may be applied, includes a pro ucer AV of .any approved form, a'scrubberB connected inthe usual manner with said producer, and the 'usual means, consisting of a suitable exhauster, (not shown), conduits and openings by means of which a current of air may be caused to enter the` producer, at a, the required gas formed in the latter, drawn through the scrubber B, withdrawn from the latter at b into the duct C and through the subsequent portions of 'the `gas-hunting apparatus which are connected with the aforementioned exhauster.

The apparatus as thus far described, is old and well-known, and whenoperating Without any further modification, au' and steam are simultaneously blown into the producer, where they come in contact with the fuel, the resulting product being what is ordinarily known as semi-water-gas. gas is withdrawn from the producer by the exhauster, the latter creating the necessary suctlon for .the introduction of the required air into the producer. Under these conditions,'the introduction of the steam is more or' less independent of the introduction of the air, and a variation in the amount of air This resulting from a change of conditions such as would produce a greater or less suction of air, and therefore a' greater or less quantity of air passing through the producer, would not aliect materially the quantit of steam introduced. As a result, the freativeploportions of air and steam would vary, and 4 the character of the semi-'Water'gas made would also vary. To overconie thisvariation in the character of the gas produced, 'I introduce at a point beyond the' producer, and in an outlet duct, means for automatif cally regulating the vintroduction of steam so as to maintain a definite predetermined relationship between the rate 'of flow vof gas produced and flowing V'through such duct, and the amount of steam introduced into the producer; said means being adapted td'iary the rate of the iow ci the steam directlyas thevariation of the rate of flow of the produced gas through said duct, thus maint-ain-v in g conditions such as will. cause a continued production of a gas 'of uniform character.

This means further that an increased production of gas must be coincident with an increase in the introduction of air into the producer and likewise with an increase inA the consumption of `fuel. To accomplish this result, I provide an adjutage F, which may be locatedjn anyconvenient part of the apparatus and inthe path of the produced gas. As shown in Eig. 1, 'this adjutage is located in the duct C, and consists preferably of a Venturitube. This adjutage is connected by means of the twoi'fnipes f f, with a prcssure-operateddevice G, said device including a diaphragm g, which is operated as a result of the difference in pressure created in the Venturi-tube. This diaphragm is connected with a valve H, located in the steam pipe E, andthis part of the apparatus is arranged so that a reduced rate of flow 0E gas through the adjutage will impart to the steam valve a closing movement. It will therefore be seen that as the rateof ow of,

the gas increases or decreases the duct C,

the amount of steam introduced into'the producer will correspondingly increase or decrease, and a constant relation of Athe amount of steam and air introduced linto the yproducer thus maintained.

Instead of 'a .Venturi-tube, an ordinary bafllefplate J may be introduced in the path dof travel of the as, as illustrated in Fig. 2,

pointer j an lthe position vof t e baille-plate may be deavnd this baleatemay be provided With ladu'ated arc j', whereby y'term:ned,' the said plate being mounted so 'that it may be set in ,dilferent fixed posi- ,15'

tions, as-will be readily understood. t. In Fig. 3 I have illustrated a modified ,form of apparatus embodying my 'inven- .1 tion, which varies fromlthat above described ,that instead of controlling the liow of steam directly by means of the valve H, said valve is arranged to control the flow of water through a pipe K,which feeds alilashboiler L. This boilerisupplies the 'steam to vthe producer A. By means of thisjconstruction, an increase or decrease in the flow of gas through the pipe C'willincrease or decrease the amount of water sup liedl to thel boiler, and hence, increase or Idecrease f the amount of steam supplied to the l. pro- 30 .e

ucer. Having thus l fully "described ,invention, what I claim and desire to secure by Letters Patent is:

1. In an apparatus for the `manufactureI of gas, the combination of a gas producer; meansjor introducing steam into the latter; means for introducing air into said producer, and means controlled entirely by the n velocity of the gaseous'current after leaving l the producer, for maintaining a definite rei 'lationship between the rate ottiow of the gas produced and the rate of flow of ysteam into the producer.

2. In apparatus for the manufacture of gas, the combination of a gas producer,` means for mtroducmg steam into the-latter; means for introduclng a1r into sald pro-v` ducer; and means interposed the path ,of movement of the gas after leaving the producer and actuated by the flow of the as passi it, for maintaining a definite re a tionshlp between the rate of How of thelgas steam controlling the steam supply and controlled by said differential Vpressure-means.

"4. v`In an apparatus for the manufacture of gas, the combination of a 'gas producer; means for introducing steam into the latter; means for introducing air into said prorducerl and an ,adjutage interposed` in the path ofemovement of the rgas-after leaving said producer; a ressure-operated 'device connected with 'sai adjutage and controlled I bythe difference of pressure created-by the latter; and a valve controllingjthetlow -of said pressure controlleddevice.
